Welcome to this companion video accompanying the "Custom Characters" video, which was episode 2 in my "Thinking In 6502" series. Here, I take a closer look at some of the topics covered in that video, including how to write better loops by leveraging the properties of 8-bit mathematics, as well as a deeper dive into operating system subroutines - and how to work without them, if you're brave enough!

As ever, while this video is aimed at the more advanced 6502 viewer, don't let that put you off: much of what I look at in this companion series is the result of going down rabbit holes initiated by the original "Thinking In 6502" video, so if you, too, want to explore a little more deeply, please come and join me!
